Results for "zero"

Absolute zero is the temperature (-273.15C) at which all motion in matter stops and is thought to be unreachable. But recent experiments using ultracold atoms have measured temperatures that are, in fact, negative in absolute temperature scale.
The journey there, however...

PreludeFor some reason, it seems that there cannot be just „nothing“, in a philosophical and physical view of existence.
“Nothing” not in the sense given by Lawrence Krauss, but in the sense of the opposite of “something”.
If there is no “som...

This is an excerpt of a discussion in the Facebook Physics Group "Grand Unification Theories in Theorectical Physics" (GUT Group) in Facebook. The discussion was about the question, whether the zero is a constant.
Students there tended to the opinion, the zero would be a constant.I ...

The Zero in PhysicsZero in physics is a quantum threshold between existence and non-existence which is basically the "same", but distinguishable by the speed of light threshold (BH to photon mediation for particles (QCD): - infinity to + infinity is the range for zero, existence means &nbsp...

Summary for Students and CEOs
There is no zero as such, when you want to explain phenomena which have no direct "FTL" connection, you may apply time dependent models, for instance when you explain the physics for car driving this is sufficient, but when you want to explain phenomena like gravity...

In physics, an expression equaling zero means, the equation is "true", but what is Zero, and what is "true"?
Zero is about an inner infinity notion, stretching the lower and upper boundary of zero to (+/-) infinity. It is about the absolute zero of the quantum vacuum.
An e...
